摘要
The invention proposes the drawing and deposition of liquid droplets while preventing any contact with the ambient air before the liquid is deposited, by providing a device which can be closed, and which can be supplied to the user in the form of a pre-filled cartridge. In a preferred embodiment of the invention, the device for drawing and depositing droplets ( 100 ) of at least one liquid ( 32 ) comprises an outer tube ( 101 ) with an opening ( 107 ) at one of the ends thereof, a flange ( 109 ) defining the opening ( 107 ), a rod ( 111, 211, 221 ) which can slide inside said outer tube ( 101 ), an inner volume ( 117 ) between said rod ( 111, 211, 221 ) and the outer tube ( 101 ), a capillary-sized open port ( 119 ) in the wall of said outer tube ( 101 ), and a closure element ( 113, 213 ) for closing said opening ( 107 ), connected to said rod ( 111, 211, 221 ). According to the invention, when said rod ( 111, 211, 221 ) is in a forward end position, said closure element ( 113, 213 ) comes into contact with the flange ( 109 ) and thus hermetically closes said opening ( 107 ) and, when said rod is not in this end position, a capillary-sized passage ( 115 ) enables the inner volume ( 117 ) to communicate with the outside.
